For the past several days the number of relays measured by my bwuath (whose data is given my maatuska) have been slowly declining. Originally I had an alert when it was below 8800, a few days I noticed it going below that. By today it's decreased to below 8700 to 8664.
It's not the lowest bwauth measuring, but I don't see anything obviously wrong with my bwauth to indicate the decline. (The number I mentioned is number of lines in the bwscan.V3BandwidthsFile file, not the measured relays that make it into the consensus - but the comparison I just made did use the consensus count.)
I wanted to send this email as a potential advance notice; but also ask if there had been any discussion of the bwauth system in Valencia, and if there is any current planned improvements in it.
